VEHICLE SPRING.

Application filed January 12, 1922, SerialNo. 528,768. neneweaiira 31,1923.

To all whom it may concern;

Be it known that I, GEORGE. sort, a citizen of the United States,residing at Greene in the county of Renville and State of h orth Dakota,have invented certain new and useful Improvements in Veliicle Springs;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains'to make and use the same.

This invention relates to an improved vehicle spring and one object ofthe invention is to provide improved means for connecting the springwith the side bar of a vehicle chassis or frame, the means forconnecting the spring with the chassis being such that the spring willbe permitted of universal movement and thus permitted to have propermovement without being bent out of shape or caused to work loose.

Another object of the'invention is to so construct the spring that aball or spherical bar of a vehicle chassis by means of the im' V V I Vby means of bolts, 20 at its outer end and element carried by a pin ofthe vehicle frame may fit into a socket formed in the master leaf of thespring and held in this socket by means of a cap having connection withthe end portion of the master leaf and provided with a socket positionedopposite the socket of the spring and receiving the ball. 7

Another object of the invent-ion is to provide a structure of thecharacter described in which the cap may besecurely but releasably heldin engagement with the master leaf of the spring and brought into properengagement with the bearing ball so that the spring may havethe desiredamount of movement but at the samejtime be prevented from moving toofreely. Another object of the invention is to so construct thisstructure that ,the sockets of the spring and cap into which the bearingball fits may be formed by stamping and pressing the spring and cap toform the de sired bearing.

This invention is illustratedin the accom panying drawing, wherein:

Figure 1 is a view partially in section and partially in elevation andshowing a spring construction having connection with the side provedconstruction. Y

Figure 2 is an enlarged longitudinal sectional View through the outerend portion of R. RICHARD- I a spring and the portion of the chassisside. 2

in a modified construction. V

Figure 7 is a partial end view of the form shown in Figure .6. Theimproved construction whereby a spring may be connected withthe side barof a vehicle chassis has beenshown in con .iiection with a spring of thetype disclosed in my co-pe'nding application having Serial No. 491,253,filed August 10, 1921; The

springs which are indicated in general by the numerals 1 and 2 extendfrom the block 3 of the axle 4 and are secured in place by bolts 5 whichfurther serve to retain in place the plate 6. This plate 6 is provided 1at one end with an eye 7 for engagement with a spring 8 which isconnected at its upper end with an eye 9 formed upon one of theleavesofthe spring 1. Each of the springs is provided with a master leaf 10;the outer end of which is tobe connected with the side bar 11 ofthcchassis'by means of the improved joint construction which will nowbedescribed. i

A bolt or pin 12 is carried by the'side bar 11 of the chassis andcarries a ball 13 which in the form shown in Figs. l'through 6 is placedupon this bolt 12 between the de'-" pending side flanges of the siderail 1.1 and a pin or other similar fastener 14. Spacing washers 15 areprovided upon this bolt between the ball and the side flanges ofgthe' vside rail thus permitting of free rotary movement when the securing nut16 of the vwill be held against movement thereon by I TOO and pressed toprovide a cup or socket "17 which receives the bearing ball 13. A capplate which is also stamped and P-IGSSGdItO provide a cup or pocket 19for receiving ball bearing 13 fits againstlt-he outer end" portion ofthe master lea-f and'is secured cap. The cap will thus be securely'heldin place upon the outer end portion of the master leaf and since thebearing ball is positioned between the cups or sockets 17" rail 11 andis provided atone end with a spherical head 23 which takes the place ofthe bearing ball 13. An enlarged spacing element 24 is provided betweenthe spherical head 23 and the depending side flange of the" side bar 11sothat when the securing nut 25 which corresponds to the securing nut 16is tightened, this ball or spherical head 23 will be spaced from theside bar. It will be readily seen'tha-t With either construction,

the outer end portion of the spring will be mounted by a oint permittingof universal movement and that therefore the spring will not be twistedout of position or bent out of shape. When it'is desired todisconnectthe spring from the side bar of the automobile chassis, it issimply necessary to reouter end portions of the springs Will be releasedand easy removal permitted.

I claim:

1. In a structure for connecting a. spring member with'a frame memberhaving spaced side flanges, a master leaf for the spring member havingits outer end portion provided 7 with a socket, a stem carried" by andextending between the flanges of the frame member, a bearing ballcarried by said stem and fitting into said socket, and a cap connectedwith the outer end portion of the master leaf and having a socketreceiving the bearing ball whereby the spring will have its outer endmounted for universal movement.

2. The structure of claim 1 having the cap and outer end portion or themaster leaf extending between the side flanges of the frame member, thestem being passed lease the clamps 21 and bolts 20 and the 1' throughthe flanges and the bearing ball.

carried by the stem. between the flan 3. The structure of claim 1 havingthe V stem passed through the flangesand the bearing ball carried by oneend of the stem to one side of the frame member and forming a head forthe stem. 7

in testimony whereof I have hereunto set my hand.

GEORGE R. RICHARDSON.
